Hi,

*1) "Success" 5.2.0-2 with device_tree from kernel 4.19:
Kde runs very well and stable. The exception is the Hdmi audio which
does not work.
shutdown -h now // It does not disconnect the power to the monitor. It
leaves the monitor on with the text (last row): "reboot: System
halted"
shutdown -r now // It does not restart. It leaves the monitor on with
the text (last row): "Reboot failed -- System halted"
Shutdown processes:

before "A stop job is running for"...
Rpi3b logs for different configurations (in a search for hdmi audio problem):

Problem:
BugNo 935456 (this): No GPU hardware detected with kernel 5.2 for
Rpi2b and Rpi3b
Error message: "bcm2835-power bcm2835-power: Timeout waiting for
grafx power OK"
BugNo 939633: Rpi3+ hangs with kernel 5.2 device_tree
Error message: "bcm2835-power bcm2835-power: Failed to disable ASB
master for v3d"
Solution:
Use "kernel 5.2.0-2 with device_tree from kernel 4.19".
We are back to functional and stable environments (armhfCard and
arm64Card) for all Rpi:s.
The exception is Hdmi audio which works in kernel version 4.19 for
both armhfCard and arm64Card, but not in 5.2.
The Hdmi audio needs yet to be fixed.
Best Regards,
Evald
